    摘要： A process for producing a dispersed-oxide-containing alloy in which oxide particles of one or more additive metals are dispersed in a matrix metal. The process, which is for producing a dispersed-oxide-containing alloy, comprises (a) a step in which a powder or wire of an alloy comprising a matrix metal and one or more additive metals is produced, (b) a step in which the alloy powder or wire is introduced into a high-energy ball mill together with water and the contents are agitated to thereby oxidize the additive metals contained in the alloy powder with water and form dispersed particles, and (c) a step in which the alloy powder or wire after the oxidization is shaped and solidified. It is useful especially for the production of a dispersed-oxide-containing alloy in which the free energy of oxide formation of the matrix metal is higher than the standard free energy of formation of water and the free energy of oxide formation of the additive metals is lower than the standard free energy of formation of water.
